I've got some questions before i run off and by my MBP. 1) I have two alternatives to choose from. Either I go for the 2.2 MBP and upgrade to 4 Gb ram, or I go for the 2.4 version, but then i cannot afford the ram boost. Im planning on using it for some 3D rendering, but not hardcore. Then I'll probably play some games too, but which one of my alternatives will do the most difference? 2) Is there any big difference in sharpness etc in the glossy screen compared to the matte? Ty all.
